What 375.505(c) means in plain language
375.505(c) addresses requirements related to vehicle and equipment maintenance or operational compliance within the FMCSR framework. While this code appears in the Federal Motor Carrier Safety Regulations, citations for it remain extremely uncommon—underscoring that most fleets manage compliance in this area successfully.
The regulation focuses on ensuring that equipment and vehicle systems meet federal standards during operation. Violations typically involve failure to maintain or properly operate specific vehicle components or systems that directly affect safety. Understanding your citation requires reviewing the specific equipment or system noted on your inspection report.
What our enforcement data actually shows
Our inspection records show that 375.505(c) is one of the rarest citations in the FMCSR database. Across 13 million inspections, we have documented only 59 all-time citations for this code, with zero citations in the last 12 months and zero in the last 90 days. This places 375.505(c) at rank #1576 of 3,036 FMCSR codes by citation volume.
None of the 59 drivers cited for 375.505(c) were placed out of service, resulting in a 0.0% out-of-service rate. This stands in stark contrast to the all-FMCSR average of 31.4%—meaning that when inspectors do cite this code, they typically do not deem the violation severe enough to immediately remove the vehicle from service. The rarity of citations and the absence of OOS actions together suggest that this violation is either caught infrequently or represents a lower-severity finding in roadside inspection practice.
Who gets cited most
Our inspection records do not include state-level breakdowns for this citation volume, so we cannot identify the top three states. However, examining carrier data shows that RED CARPET MOVING AND STORAGE INC (USDOT 3665854) accumulated the most citations with 3 instances over our all-time database. The remaining citations are distributed widely: FEDERAL EXPRESS CORPORATION, PARKINS TRUCKING LLC, INTERWEST MOVING & STORAGE INC, CENTRAL TRANSPORT LLC, ROOFLINE INC, HILL ROM COMPANY INC, METEOR EXPRESS INC, TNT MOVERS LLC, and ABF FREIGHT SYSTEM INC each appear once. This distribution indicates that 375.505(c) citations do not cluster within a small number of carriers—they are genuinely scattered across the industry.
Vehicle makes cited most often include FRHT (6 citations), WANC (3 citations), HINO (2 citations), FONA (2 citations), FORD (2 citations), and PTRB (2 citations). The variety of makes suggests that no single vehicle type is disproportionately vulnerable to this citation.
How severe is this compared to similar codes
When comparing 375.505(c) to peer codes in the same category, the contrast is striking. 376.11(d)(1) has logged 6,383 citations with a 0.0% OOS rate, making it far more common but equally non-severe in enforcement outcome. The code labeled "999" shows 4,802 citations but a 12.1% OOS rate, indicating that when cited, it sometimes results in out-of-service actions. 107.620(b) has generated 2,120 citations with a 0.2% OOS rate—still considerably more frequent than 375.505(c) but with minimal severity.
In summary, 375.505(c) is significantly rarer than most peer codes, and its 0.0% OOS rate matches or beats several comparable violations, suggesting inspectors view it as a lower-tier issue when it does appear.
How to avoid it
Because citations for 375.505(c) are so infrequent and no co-occurring violation patterns are documented in our database, the best prevention strategy is to follow standard pre-trip and in-service inspection practices:
- Perform a thorough pre-trip inspection before every shift, paying special attention to all equipment systems and components. Use your carrier's inspection checklist and document all findings, even minor ones.
- Know your vehicle's maintenance schedule. Whether you operate a FRHT, WANC, HINO, or any other make, ensure that routine maintenance is completed on time. Missing oil changes, belt replacements, or fluid top-offs can trigger equipment compliance violations.
- Test all operational systems during pre-trip. Verify that lights, wipers, mirrors, seat belts, and any specialized equipment operate correctly before departing.
- Report defects immediately. If you discover a mechanical issue, stop operation and notify your dispatcher or maintenance team. Do not attempt to work around equipment problems.
- Stay current on regulatory updates. Your carrier should keep you informed of any changes to FMCSR requirements affecting your vehicle class and cargo type.
- Communicate with your inspector. If stopped for an inspection and questioned about a specific component or system, answer directly and show documentation of recent maintenance. Inspectors are more likely to view your vehicle favorably if records are current and organized.
